Sudoku Puzzle Hub

Short sudoku lessons from SudokuPuzzleHub, the free puzzle site. Every Monday there's a Find the Move Short: one board, one sure move, and the reason it works. 

Twice a month there's a longer lesson, starting with sudoku for kids on 4x4 and 6x6 grids, then Killer sudoku and the classic solving techniques. Every puzzle we show is checked to have exactly one solution, so you never need to guess.
